ST. LOUIS, MO (KTVI)-The cousin of a 9-month-old baby who was killed in a house fire Wednesday remains in critical condition. The four-year-old boy is suffering from smoke inhalation. The child's one-year-old brother is in fair condition.

The boys' mother and her boyfriend are in critical condition as well.

According to our partners at the St. Louis Post-Dispatch, some believe it may have been an electrical fire because the lights weren't working when the victims tried to escape.
